Fabrication of tubular ZnO by vesicle-template fusion

Zinc oxide microtubes were synthesized by hydrothermal method. The cooperation activities of surfactant cetyltrimethylammonium bromide (CTAB) and bidentate ethylenediamine ligand were found to be appropriate for the formation of final tubes. The morphologies and structures of the samples were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), and scanning electron microscopy (SEM). A possible vesicle-template elongating fusion mechanism was proposed and discussed.
